I'm having some trouble testing my application. We have some pretty complex
hierarchical data being created and to do effective testing I want to put
the Database into a known state before running any tests, whether that's
empty or with a predefined set of data depends on the specific tests being
run.
GWT Junit tests don't allow you to perform async requests during the
beforeMethod.
To try and get around some of this I'm trying to run all my junit tests
from my own handler. The process works kind of like this:
A. load the list of GWTTestCases
B. Ask each test whether it wants an empty database or a predefined data
set in the DB and create the preconditions. All my tests extend a base
class which extends GWTTestCase and has a series of flags that let it
specify the required DB state.
C. run the GWTTestCases as normal.
The first 2 steps are pretty straightforward but the third one is throwing
me. I can't get any of the tests to run.
I'm sure I'm not running the tests properly.
I'm getting a combination of errors both:
The test class 'com.scalebase.management.client.DummyTest' was not found in
module 'com.scalebase.management.ScaleBaseManagement'; no compilation unit
for that type was seen
And
GWTTestCases require a name;
"null(com.scalebase.management.client.DummyTest)" has none. Perhaps you
used TestSuite.addTest() instead of addTestClass()?
Can anyone give me some guidance in how to run the GWT unit tests
programatically? Also should I be running the tests class by class or
should I use reflection to try and run them method by method? I'm not
really sure how normal tools handle these issues.
Any help would be greatly appreciated
Thanks
My class looks like this:
public class NewApproach
{
private ServersService ss;
private List<TestBase> tests;
private void loadTests()
{
tests = new ArrayList<TestBase>();
tests.add(new DummyTest());
}
private void clean() throws Exception
{
ss = new ServersService();
ss.clean("1");
}
private TestResult runTest(TestBase tests) throws Exception
{
if(tests.isCleanBeforeRunning())
clean();
TestResult tr = new TestResult();
tests.run(tr);
return tr;
}
private void printResults(TestResult tr)
{
int passes = tr.runCount() - (tr.failureCount() + tr.errorCount());
System.out.println("Ran " + tr.runCount() + " tests " + passes + "
passed");
System.out.println();
while(tr.errors().hasMoreElements())
{
TestFailure tf = tr.errors().nextElement();
System.out.println(tf.failedTest().toString() + " error");
System.out.println(tf.exceptionMessage());
System.out.println(tf.trace());
tf.thrownException().printStackTrace();
}
while(tr.failures().hasMoreElements())
{
TestFailure tf = tr.failures().nextElement();
System.out.println(tf.failedTest().toString() + " failed");
}
}
public void runTests() throws Exception
{
for(TestBase test: tests)
{
TestResult tr = runTest(test);
this.printResults(tr);
}
}
public static void main(String[] args) throws Exception
{
NewApproach na = new NewApproach();
na.loadTests();
na.runTests();
}
}
